VALVE AND RESERVOIR FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 373,015, dated November8, 1887.

Application filed March 31, 1884. Serial No. 126,132. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM S. COOPER, a citizen of the United States,and a resident of Philadelphia,Pennsylvania,haveinvented certainImprovements in Reservoirs and Valves for Water-Closets, of which thefollowing is a specification.

The object of my invention is to overcome the objectionable gurgling orroaring noise usually caused by the escape of water or air through theoverflow-pipe of a water-closet reservoir; and this object I attain bythe use of a float-valve adapted to close the entrance to saidoverflow-pipe when the level of water in said reservoir is low, but freeto rise as the level of water rises, so as to permit the escape of thesurplus water through the overflowtube.

In theaccompanying drawings, Figure 1, Sheet 1, is a longitudinalsection of my improved water-closet reservoir, the valve beingclosedthat is to say, in the position which it occupies when the valveof the closet has been closed and the flow of Water has ceased. Fig. 2,Sheet 2, is a section of the reservoir with the valve in the positionwhich it as sumes when the valve of the water-closet has been opened;Fig. 3, a section of part of the reservoir, showing the valve as itappears after the valve of the water-closet has been closed, but beforethe flow of water has been cut off; Fig. 4:, a transverse section ofpart of the reservoir on the line 1 2, Fig. 2; Fig. 5, Sheet 1, asection of part of the valve in adifferent position from that shown inFig. l, 2, or 3; and Fig. 6, a sectional plan on the line 3 4, Fig. 1.

A is the reservoir, in the bottom of which is a depression, a, separatedfrom the main reservoir by a partition, I), resting upon a shoulder, c,and confined by a stud-bolt and nut, said partition forming beneath thereservoir A a chamber, B, which can communicate with the reservoirthrough an opening, I), in the partition, this opening being surroundedby a projecting ring, cl, which forms a seat for a valve, D, the stem Dof the latter being connected by any suitable means to thevalve-operating lever of the water-closet.

In the bottom of the casing a of the chamber B is an opening, 6, and tosaid casing is secured a chest, F, the packing-ring f, which intervenesbetween the casing a and the upper end of the chest F, surrounding theopeninge and forming another seat for the valve D.

Forming part of the valve is a tubular projection or plunger, D providedwith slots the lower end of this tubular plungerbeing furnished with apacking-ring, h, which fits snugly in a cup, G, suspended within thevalve-chest F, the cup being of less diameper than the chest andsupported therein by a notched ring, so that w'ater can flow freelybetween the two.

To the lower end of the tubular plunger D of the valve D is adapted avalve, H, consisting of a disk, 2', with a projecting flexible ring, 1',this valve having a stem, m, and being sup ported by a spring, m,interposed between a spider, m", in the cup G and adjustable nuts m atthe upper end of the stem. The disk i has an opening, 12, formed in it,and on the bottom of the valve is a strainer, 19, of perforated plate orwiregauze.

Secured to and projecting upward from the valve D is a tube, J, whichcommunicates through the valve with the tubular plunger D" of the same,and on the upper end of this tube rests a float, K, consisting in thepresent instance of a sheet-metal cup with a central tube, K,surrounding but somewhat larger in diameter than the valve-rod D.

A weight, M, surrounds the tube J and rests upon a ring, 8, on saidtube, and a screen or cage, W, ofperforated plate or wire-gauze, issecured to the partition a, and has an opening in the top for thepassage of the weight, this screen serving to prevent the access to theopening b of sticks or other foreign matter tending to interfere withthe operation of the valve D, which is as follows: When the valve of thewatercloset is closed, the valve D is in its lowest position and restson the seat f, as in Fig. 1, the other parts being also in the positionthere shown, and the chamber B being filled with water. On operating thevalve lever of the closet, so as to open the valve of the same, thevalve D is raised against the seat 'd, as shown in Fig. 2, thuspermitting the water in the chamber B to flow down through the chest Fto the closet, the volume and force of the flow being sufficient toeffectually fiush and clean said basin, air being slipplied to thechamber B through a pipe, P,

which extends above the level of water in the reservoir A, and isfurnished with a hood, 1?. During the upward movement of the valve D thevalve H yields downwardly, so as to permit a free flow of water past thesameandinto the bottom of the cup, as shown in Fig. 5. \Vhen the valveof the closet is closed, the valve D is also released and permitted tofall under the influence of the weight M; but this descentis retarded,owing to the fact that the valve H closes against its seat and traps thewater in the cup G, the water thus trapped being compelled to escapethrough the platep and the opening a in the valve, so that the timewhich elapses before the valve reaches its lowerseat, f, depends uponthe area of this opening, and during all this time the water can flowfrom the reservoir A through the chamber B and chest F to the basin ofthe closet, thorough washing of which and of the soil-pipe is therebyeffected and the filling of the traps insured.

The pipe J is the overflow-pipe, whereby the water in the reservoir A isprevented fromrising above the proper level, and the function of thefloat K is to prevent the disagreeable noise which results if the wateris permitted to flow over the open top of the pipe, as usual, and alsoto prevent the roaring sound caused by a rush of air into and throughthe pipe when such action is induced by the flow of water through thechest F. The tube K.

while preventing the admission to the pipe J tube, acts as a cut-offvalve to prevent the entrance of air in largevolumes to said tube, thevalve being lifted from its seat, however, on an undue rise of the waterin the reservoir, so as to permit the surplus to escape through theoverflow-tube. This is the novel feature of my invention, the otherdevices having been shown and described simply to give a proper idea ofthe working of the reservoir.

I am aware that a water-closet reservoir has been provided with anoverflow tube the mouth of which is closed by a valve carried by apivoted arm the outer end of which is furnished with a float; but insuch case the movement of the float -must be much greater than that ofthe valve on account of the diflerenee in leverage, whereas in my devicethe valve forms part of the float and its vertical movementisco-extensive with thatof the float.

I therefore claim as my invention 1. The combination of the reservoir,its discharge-valve and discharge pipe, the overflow-pipe, and a floatseated upon the upper end of said overflow-pipe and forming a valve toprevent the intlow of air over the upper edge of the pipe, allsubstantially as specified.

2. The combination of the reservoir, its dis charge pipe, the dischargevalve, the overflow-pipe,andafloat-valve closing the entrance to saidoverflow-pipe, and having a passage of limited area through which aircan enter the overflow-pipe, all substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two sub scribing witnesses.

WM. S. COOPER.
